Hi there,
I'm trying to configure a firewall on a VM running Debian 4.0. The Hardware Node runs CentOS (kernel 2.6.9-023stab043.2-smp) with OpenVZ.
I'm using the following rules:
iptables -F
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT
iptables -A INPUT -j ACCEPT -p tcp --dport 21
iptables -A INPUT -j ACCEPT -p tcp --dport 22
iptables -A INPUT -j ACCEPT -p tcp --dport 80
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
The last rule fail with this error message:
utopia:~# iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables: No chain/target/match by that name
On my machine running Ubuntu 7.04 I can use this rules without problem. So I think this might be related with some missing kernel module, but I can't find out which. Any ideas?
Thanks, Rodrigo.
